GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent N 0. 734,546, dated July28, 1903. Application filed December 10,1901. Serial No] 86,808. (Nomodel-D To all whom it 11mg) concern/.- p v Be it known that I,HENRYHALSEY, a citizen of the United States, residing at New York city,in the county of New York andState of New York, have invented certainnew and useful Improvements in Galvanic Batteries, of which thefollowing is a full, clear, and ex,- act specification.

My invention relates to batteries; and its object is to provide abattery of simple con struction having a minimum weight and bulk andmaximum output.

The invention will be described more in detail with reference to theforms thereof shown I 5 in the accompanying drawings, in which Figure 1is a top view, partly in section, of a battery embodying my invention.'Fig. 2 is asectional elevationof the same, and Fig. 3 is a top Viewshowing a modified arrangement for moving the elements.

Referring more'particularly to the drawings, 1 represents a suitablecase divided by partitions 2 2 into aplurality of cells, each of whichcontains a suitable quantity of ex citant solution 3; A cover 4 issuitably fitted upon the top of the receptacle and preferably isarranged to be conveniently raised and lowered thereon. To the cover'"4a plurality of zinc cylinders 5, corresponding in number to the numberof cells, are attached,

the cylinders extending down into the excitant 7 solution. From eachcylinder a contact 6 extends up through the cover 4. A number of shafts7, also corresponding in number to the number of cells, are journaled inthe cover 4, flanges 8 and 9 serving to maintain the shaft in properposition in its bearing and to raise it when the cover is raised. end ofthe shaft is journaled in any suitable 4o manner in the bottom of thecell.

each cell a cylindrical carbon cup 10 is mounted upon shaft 7, the lowerend of the cup being closed and the upper end being open, but supportedupon the shaft by a copper spider 11, having a flange 12," which fitsover the top of the carbon cup. The carbon cup is of porous materialand, if preferred, may be provided with perforations 13 13. Bichro- Thelower 7 Inside mate of potassium or other-suitable depolariz ing agentis maintained Within the carbon cup 14. Upon the upper end of each ofthe shafts 7 is mounted a gear-Wheel 15,'into which meshes a pinion 16.The pinions 16 are mounted upon a shaft17,'which is journaledin bearings18 18 carried by thecover 4. Upon the end shaft 17 is a gear-wheel19,suitably geared 'to the shaft 20 of a small electric motor'2l;

Any number of cells may be employed, and they may be connected with eachother in any desired manner. In the drawings I have shown the cellsconnected in series. The terminals 6, connected to the zincelements,'are each connected by a conductor 22, which for conveniencemay be slotted, as shown in Fig. 1, and the two parts thereof clampedaround the shaft 7 by a screw 27 with the shaft 7 of an adjacent cell,shaft 7 of course being electrically' connected to the carbon elements.The main circuit from the battery will be taken from the shaft 7 of onecell at one end of the series of cells, as indicated by wire 23 in thedrawings, and from the terminal 6 of the cell at the other end of theseries, as indicated by wire 24 in the drawings. The motor 21 ispreferably connected with the terminals 6 and 7 in shunt, as indicatedby wires 25 and 26 in the drawings. The circuit maybe opened by raisingthe cover 4, and thus removing the elements from the excitant solution,or by a switch 28, which simultaneously opens or closes the main circuitand the shuntcircuit through the motor.

A modified arrangement for driving the moving cells is shownin Fig. 3,wherein the various gear-wheels 15,are arranged to mesh with each other,and one of the wheels is geared to motor 21 in any convenient manner.

In operation, the cups 10 having been filled with a depolarizing agentand the cells having been filled with excita'nt solution, the switch 28is closed, and thereupon the high initial force of "the battery isexpended to start up the motor 21, which, through the gear-wheel 19,shaft 17, pinions 16, and gearwheel 15, rotates the shafts 10, and thusrotates described.

the carbon cups. The rotation of the carbon elements operates tomaintain the excitant solution uniform and also prevents thedepolarizing of the battery. The rotation of cup 10 also operates tofeed the depolarizingagent to the battery in proportion as it is needed.The perforations 13 may be employed to aid this distribution of thedepolarizing agent, if preferred. After the motor has attained its fullspeed the output of the battery will have increased to maximum output,and as long as the rotation continues this will be maintained.

It will be understood, of course, that the above-described constructionmay be modified in various respects without departing from theinvention, and I therefore desire it to be understood that I do notherein limit myself to the precise construction shown.

Having thus described my invention, I declare that what I claim as new,and desire to secure by Letters Patent, is-

1. In a battery, the combination of a cell containing anexcitantsolution, a cover therefor, positive and negative elements, anda vertical shaft so journaled in said cover as to be removable therewithand upon which shaft is mounted one of said elements, the other elementbeing suspended from the cover and said shaft extending outside of thecell, and means for rotating said shaft, substantially as 2.
